PHP Bug Type: CGI related
Bug description: cgi 'leaks' shell_exec output to webserver
Description:
------------
When a php-cgi issues an shell_exec that outputs code that is expected to
be stored in the variable before it. The output is in fact leaked back over
the fcgi connection, which will issue a 500.
I'm using the Cherokee webserver.
Reproduce code:
---------------
$debug = shell_exec('/usr/bin/nohup /usr/bin/inkscape -z
--file='.$svgfile.' --export-width='.$width.' --export-height='.$height.'
--export-png='.$pngfile);
The work around seems to be to add:
.' 2>&1 1>/dev/null'
Expected result:
----------------
Output to be stored in $debug.
Actual result:
--------------
Outputted over the fcgi line:
00000000 2f75 7372 2f62 696e 2f6e 6f68 7570 3a20 /usr/bin/nohup:.
